His receiving numbers over his career:
2004 - 8 games, 3 catches, 16 yards, 5.3 avg
2005 - 15 games, 18 catches, 218 yards, 12.1 avg
2006 - 16 games, 31 catches, 222 yards, 7.2 avg
2007 - 15 games, 23 catches, 164 yards, 7.1 avg
I don't recall seeing him drop many passes. The Steelers haven't thrown much to the running backs since Bettis was added to the roster. Take a look at his numbers for yourself: http://sports.espn.go.com/nfl/players/s

You have to go back to John L. Williams in '94 to find a season when the Steelers really threw to the RB: http://www.nfl.com/players/johnl.willia
That's all I can think for RBs of at the moment. I couldn't even find stats on Jon Whitman.
Shall I continue or can we put to rest the Parker can't catch myth?
Will Mendenhall change that? Who knows...every time the Steelers draft a TE they say they will throw to them more and it never seems to work out that way...so I have my doubts.
